Yokohama's coastal position gives it a slightly cooler climate than inland Tokyo. I've tracked the temperature differences and found the bay breeze provides natural air conditioning on summer afternoons. The city's waterfront parks and Minato Mirai district are best enjoyed in September and October, when the humidity drops and the skies clear. The data supports what locals know: Yokohama's climate is a few degrees more comfortable than Tokyo's year-round.
